Description

一种氘代二氟甲硫基试剂及其制备方法和在药物分子中引入 SCF2D基团的方法
技术领域
本发明属于有机合成技术领域,具体涉及一种氘代二氟甲硫基试剂及其制备方法和在药物分子中引入SCF2D基团的方法。
背景技术
作为一种标记技术,氘化已被广泛应用于有机合成、机理研究、药物代谢分析、核磁共振光谱以及药物发现和发展。氘是自然界中氢的一种稳定的非放射性同位素。由于其原子质量比氢大,C-D键比C-H键更稳定(6-9倍)。用更稳定的碳-氘键代替碳-氢键可以大大增强代谢和药代动力学特性,同时保持药物分子的效力和选择性。用氘取代药物分子中的氢可以减慢系统的清除率,延长药物在体内的半衰期。同时,可以封闭代谢部位,减少有毒代谢产物的产生,达到降低药物毒副作用的目的。近年来,研究者们对氘化药物进行了深入研究,2017年,FDA批准了第一个氘化药物——氘代丁苯那嗪(Austedo),极大地推动了氘化合成方法的发展。
通过该种氘代二氟甲硫基试剂(PhthSCF2D)可合成出多种类型的含有SCF2D基团的活性药物分子,因此该试剂在今后的药物合成应用中前景广阔。
目前如何用氘取代药物分子中的氢仍是研究着们面临的巨大难点,我们对已报道的二氟甲硫基试剂PhthSCF2H的合成方法进行了深入研究,并创造性的探索出合成氘代二氟甲硫基试剂PhthSCF2D的工艺方案,我们认为这是在合成SCF2D试剂上取得的重大突破。
文献(A Two-Step,One-Pot,and Multigram-Scale Synthesis of N-Difluoromethylthiophthalimide[J],Org.Process Res.Dev.2017,21,1383-1387)公开了制备PhthSCF2H的操作方法,产率虽达到了76%,但该工艺方法中无法实现通过氘对氢的替换获得高氘代纯度的氘代产品,且反应温度低至-30℃,不利于生产操作。

文献(N-Difluoromethylthiophthalimide:AShelf-Stable,ElectrophilicReagent for Difluoromethylthiolation[J],J.Am.Chem.Soc.2015,137,10547-10553)也报道了制备PhthSCF2H的操作方法,该方法虽然产率较高,但其操作较为繁琐无法实现大量生产,同时也无法实现氘对氢的替换获得大量高氘代纯度的氘代产品的目的。

(2)本发明制得的PhthSCF2D可作为亲电试剂应用于多种亲核底物,应用范围广泛。
(3)本发明制得的PhthSCF2D可作为自由基试剂,通过光催化反应实现烯烃和醛类的“SCF2D”化,自由基反应是SCF2H(D)反应类型的突破;
(4)本发明将“F”的亲脂性和“D”的代谢稳定性成功结合在药物应用中,具有广阔的前景;
